Change the test to use a custom scheduler so there is better control on when the carrier threads terminates. Also convert test to TestNG so that all test cases can be run in the context of a virtual thread.

-------------

Commit messages:
 - Convert to TestNG and run all tests on a virtual thread
 - Merge
 - Change test to use custom scheduler, easier to test reliably
